This is an anti-theft weight. Use it as a base for U-locks, chain locks, etc. You can use it without getting in the way, even in bicycle parking areas with limited space, by placing it in front of your bike. It's handmade from concrete, so there may be cracks and it may not look perfect, but its effectiveness and power are not compromised at all!! Reinforcing bars are also inside, so it won't break unless you drop it!! You can even bury it‼ Weight: Approximately 20 kg. Protect your precious treasures from thieves!! ✻Image 4 is for illustration purposes only✻ It will be shipped wrapped in newspaper and plastic wrap. Also, please be careful as small pieces of debris will come off when you unwrap it!! There is a little paint on the surface, but it's not noticeable. Thank you for your interest.
